A DNS (Domain Name System) is used to convert the domain names into IP addresses. It is a huge database where all the domain names and their IP addresses get stored. The best DNS servers offer a slew of features like fast browsing speed, top security, and reliability. DNS server is also known for filtering specific types of websites and defending the systems from phishing attacks.

We normally use domain names to access the various sites. While we as humans can understand this, the computers view it very differently. They recognize the domains by their IP addresses and that is where the DNS server is useful.

How do DNS Servers Work?

When you want to access Google.com, you will simply type the domain name of the website in the address bar of your browser. After you type Google.com and hit enter, it goes to the DNS server and takes the IP address ( for Google) associated with the domain name you searched for. Then, it connects to the webserver, loads all the content from there, and displays the relevant information on your web browser.

Here’s a short overview of the working of a Domain Name Server.

ISP Default DNS Server Vs DNS Server?

If you are wondering why we use another DNS server rather than use the default ISP DNS server, then here is the answer. Using the best DNS servers means getting extra security, service, and much more in terms of features.

  • Speed: Default server lacks in speed, so using a public DNS server will enhance the speed of your internet, making browsing easy.
  • Stability: The Public DNS servers are specially optimized to take a huge amount of load without affecting the speed with no downtime to increase productivity.
  • Security: Some third-party DNS servers provide an extra layer of security like protection and filters. Thus, malicious and phishing attacks are easily avoided.
  • Geo-Protection: Using a DNS server can restrain the restrictions and various inspections so that you have access to the services regardless of the location. For example, if it says, “This video is not available for your country” on YouTube, you can still watch it.
  • Child Lock Feature: Many DNS servers help you to block adult or harmful sites from children.

Also, sometimes, with the default ISP provided servers you may face common DNS issues. In such cases, you may need to use another DNS server.
